Title: Manufacture of azo-dyestuffs on the fibre
IPC: D06P1/649
Filed: 1934-11-14
Abstract: Azo dyes are made on the fibre by using for the grounding operation a solution or suspension of a coupling component in which the quantity of alkali necessary for the formation of a stable solution or suspension of a salt-like product is wholly or in part replaced by a water-soluble nitrogenous base of the general formula R1--NH--R2 wherein R1= H or an aliphatic radical containing not more than four carbon atoms which is not linked to the nitrogen atom by a CO-group, and R2=a similar aliphatic radical, or by a salt of one of these bases having an alkaline reaction.  The process is useful in dyeing acetyl celluloses, wool, natural silk or mixtures thereof with one another, or with vegetable fibres or regenerated celluloses.  In examples: (1) acetyl cellulose is grounded in a solution containing the anilide of 2 : 3-oxynaphthoic acid, alcohol, caustic soda solution, oleylmethyltaurine and dicyandiamide, squeezed, developed with 4<1>-methoxydiphenylamine-4-diazonium chloride, rinsed, treated with a solution containing oleylmethyltaurine and sulphuric acid, rinsed, soaped and rinsed (navy blue); (2) a mixed fabric of cellulose acetate and viscose is grounded as above with the p-anisidide of 2 : 3-oxynaphthoic acid and using guanidine carbonate instead of dicyandiamide and developed as above with diphenylamine-4-diazonium chloride (navy blue); (3) wool is grounded as in (2) with the 2-methyl-4-chloranilide of 2 : 3-oxynaphthoic acid, the solution containing formaldehyde in addition, developed with diazotized 1-amino-2-methyl-4-chlorobenzene containing acetic acid and the ethylene oxideoctodecyl alcohol reaction product, and treated with solutions containing oleylmethyltaurine (red); (4) and (5) acetyl-cellulose is treated at 60 DEG  C. in a bath containing oleylmethyltaurine, guanidine carbonate, the p-chloranilide of 2 : 3-hydroxy carbazole carboxylic acid or b -naphthol, alcohol, caustic soda, 1-amino-2-methoxy-4-nitrobenzene and acetone and developed with nitrite and acid (red-brown and red respectively); (6) m-aminoazotoluene is diazotized on acetate artificial silk and the bluish-red shade developed with b -naphthol dissolved in guanidine carbonate; (7) acetyl cellulose is grounded in a solution containing the 2-methyl-4-chloranilide of 2 : 3-oxynaphthoic acid, alcohol, caustic soda, oleylmethyltaurine and ethylamine and developed as in (1) (blue); (8) acetyl cellulose is grounded in a bath containing oleylmethyltaurine, a mixture of guanidine, guanidine nitrate and guanidine carbonate (obtained by reaction of caustic-soda and sodium carbonate on guanidine nitrate), the p-anisidide of 2 : 3-oxynaphthoic acid, alcohol, caustic soda and 1-amino-2-methoxy-4-nitrobenzene and the colour developed with nitrite and acid (bluish red).  Other bases specified are mono- and di-methylamine, diethylamine, and ethanolamine.  Specification 348,269 is referred to.
Patent GB-1395148-A (GB)
Title: Temperature control of a heating element
IPC: G05D23/22
Filed: 1971-07-13
Abstract: 1395148 Automatic control of temperature BLACKHAWK ELECTRONICS Ltd 11 July 1972 [13 July 1971] 32802/71 Heading G3R [Also in Division H3] Power to a heating element is gradually increased or decreased in response to the production of a sawtooth waveform by a generator controlled by a signal indicating temperature of the element, and a delayed signal produced in response to removal of power from the element. As shown, power to heating element 1 e.g. in a soldering iron or oven, is controlled by power amplifier 8. If the temperature, as sensed by a thermocouple connected to terminals 2, is below a value set by potentiometer 17, the output of long-tail pair 3, 4 is insufficient to actuate Schmitt trigger 5, whose output remains high, this output being applied to a ramp generator 6 to progressively turn amplifier 8 on via amplifier 7. At a pre-set temperature, or above, the thermocouple output is high enough to allow the longtail pair 3, 4 to trigger 'on' the Schmitt trigger 5, whose output falls, and ramp generator 6 progressively turns amplifier 8 off. Transistor 11  turns off as amplifier 8 is turned off, and allows capacitor 12 to charge until, after a time delay, transistor 15 is biased on to turn the Schmitt trigger 'off' and amplifier 8 is turned back on until the pre-set temperature is again reached.

Abstract: Articles of aromatic polyesters, cellulose acetate or cellulose triacetate are printed with a paste containing a dispersed dye and 1-10% based on the weight of finished printing paste of a water-soluble polyvinyl ether.  Advantageously polyvinyl methyl ether is used having a K-value of 40-50 although polyvinyl ethers containing low molecular weight hydroxyalkyl radicals may also be used.  Copolymer ethers containing small amounts of other monomers especially those which improve water-solubility such as maleic anhydride as well as mixtures of any of the above may be employed. Other usual additives may be present, those specified being British gum, tragacanth, crystal gum, sodium carboxymethyl cellulose, the sodium salt of a dialkylsulphonimide with about 10 carbon atoms in each alkyl radical, sodium chloride, sodium sulphate, salts of ligninsulphonic acid and naphthalene sulphonic acid/formaldehyde condensation products.  Printing may be followed by drying with hot air and fixation with hot air or steam at about 190 DEG C.  Examples are given employing disperse dyestuffs from the monoazo and anthraquinone series.
